Parece que esta é uma simples questão de sudo.
sudo openvpn client.ovpn funcionou como um tratamento.
Estou tentando configurar um servidor de acesso OpenVPN na AWS usando a AMI do mercado, mas estou lutando para me conectar a ele.
O servidor de acesso está funcionando. Eu também adicionei um usuário com login automático e gerou as configurações e os certificados relevantes do cliente.
Eu então copiei os arquivos para a minha máquina e tentei conectar usando openvpn client.ovpn , mas recebi a seguinte saída e erro,

Usando o Linux Mint e conectando através da interface do usuário do Network Manager (que não solicita um sudo pwd) - presumi que não era necessário. Acontece que esse era o problema para mim! Conectar via sudo de um terminal funcionou perfeitamente.
